2025-02-10ASoC: SOF: amd: Handle IPC replies before FW_BOOT_COMPLETECristian Ciocaltea
In some cases, e.g. during resuming from suspend, there is a possibility that some IPC reply messages get received by the host while the DSP firmware has not yet reached the complete boot state. Detect when this happens and do not attempt to process the unexpected replies from DSP. Instead, provide proper debugging support.

2025-02-10ASoC: SOF: amd: Add post_fw_run_delay ACP quirkCristian Ciocaltea
Stress testing resume from suspend on Valve Steam Deck OLED (Galileo) revealed that the DSP firmware could enter an unrecoverable faulty state, where the kernel ring buffer is flooded with IPC related error messages: [ +0.017002] snd_sof_amd_vangogh 0000:04:00.5: acp_sof_ipc_send_msg: Failed to acquire HW lock [ +0.000054] snd_sof_amd_vangogh 0000:04:00.5: ipc3_tx_msg_unlocked: ipc message send for 0x30100000 failed: -22 [ +0.000005] snd_sof_amd_vangogh 0000:04:00.5: Failed to setup widget PIPELINE.6.ACPHS1.IN [ +0.000004] snd_sof_amd_vangogh 0000:04:00.5: Failed to restore pipeline after resume -22 [ +0.000003] snd_sof_amd_vangogh 0000:04:00.5: PM: dpm_run_callback(): pci_pm_resume returns -22 [ +0.000009] snd_sof_amd_vangogh 0000:04:00.5: PM: failed to resume async: error -22 [...] [ +0.002582] PM: suspend exit [ +0.065085] snd_sof_amd_vangogh 0000:04:00.5: ipc tx error for 0x30130000 (msg/reply size: 12/0): -22 [ +0.000499] snd_sof_amd_vangogh 0000:04:00.5: error: failed widget list set up for pcm 1 dir 0 [ +0.000011] snd_sof_amd_vangogh 0000:04:00.5: error: set pcm hw_params after resume [ +0.000006] snd_sof_amd_vangogh 0000:04:00.5: ASoC: error at snd_soc_pcm_component_prepare on 0000:04:00.5: -22 [...] A system reboot would be necessary to restore the speakers functionality. However, by delaying a bit any host to DSP transmission right after the firmware boot completed, the issue could not be reproduced anymore and sound continued to work flawlessly even after performing thousands of suspend/resume cycles. Introduce the post_fw_run_delay ACP quirk to allow providing the aforementioned delay via the snd_sof_dsp_ops->post_fw_run() callback for the affected devices.

2025-02-10ata: libahci_platform: Do not set mask_port_map when not neededDamien Le Moal
Commit 8c87215dd3a2 ("ata: libahci_platform: support non-consecutive port numbers") modified ahci_platform_get_resources() to allow identifying the ports of a controller that are defined as child nodes of the controller node in order to support non-consecutive port numbers (as defined by the platform device tree). However, this commit also erroneously sets bit 0 of hpriv->mask_port_map when the platform devices tree does not define port child nodes, to match the fact that the temporary default number of ports used in that case is 1 (which is also consistent with the fact that only index 0 of hpriv->phys[] is initialized with the call to ahci_platform_get_phy(). But doing so causes ahci_platform_init_host() to initialize and probe only the first port, even if this function determines that the controller has in fact multiple ports using the capability register of the controller (through a call to ahci_nr_ports()). This can be seen with the ahci_mvebu driver (Armada 385 SoC) with the second port declared as "dummy": ahci-mvebu f10a8000.sata: masking port_map 0x3 -> 0x1 ahci-mvebu f10a8000.sata: AHCI vers 0001.0000, 32 command slots, 6 Gbps, platform mode ahci-mvebu f10a8000.sata: 1/2 ports implemented (port mask 0x1) ahci-mvebu f10a8000.sata: flags: 64bit ncq sntf led only pmp fbs pio slum part sxs scsi host0: ahci-mvebu scsi host1: ahci-mvebu ata1: SATA max UDMA/133 mmio [mem 0xf10a8000-0xf10a9fff] port 0x100 irq 40 lpm-pol 0 ata2: DUMMY Fix this issue by removing setting bit 0 of hpriv->mask_port_map when the platform device tree does not define port child nodes.

This wasn't a problem at the begining because __patch_mem() is not instrumented. Commit 465cabc97b42 ("powerpc/code-patching: introduce patch_instructions()") use copy_to_kernel_nofault() to copy several instructions at once. But when using temporary mm the destination is not regular kernel memory but a kind of kernel-like memory located in user address space. Because it is not in kernel address space it is not covered by KASAN shadow memory. Since commit e4137f08816b ("mm, kasan, kmsan: instrument copy_from/to_kernel_nofault") KASAN reports bad accesses from copy_to_kernel_nofault(). Here a bad access to user memory is reported because KASAN detects the lack of shadow memory and the address is below TASK_SIZE.

2025-02-09PM: sleep: core: Restrict power.set_active propagationRafael J. Wysocki
Commit 3775fc538f53 ("PM: sleep: core: Synchronize runtime PM status of parents and children") exposed an issue related to simple_pm_bus_pm_ops that uses pm_runtime_force_suspend() and pm_runtime_force_resume() as bus type PM callbacks for the noirq phases of system-wide suspend and resume. The problem is that pm_runtime_force_suspend() does not distinguish runtime-suspended devices from devices for which runtime PM has never been enabled, so if it sees a device with runtime PM status set to RPM_ACTIVE, it will assume that runtime PM is enabled for that device and so it will attempt to suspend it with the help of its runtime PM callbacks which may not be ready for that. As it turns out, this causes simple_pm_bus_runtime_suspend() to crash due to a NULL pointer dereference. Another problem related to the above commit and simple_pm_bus_pm_ops is that setting runtime PM status of a device handled by the latter to RPM_ACTIVE will actually prevent it from being resumed because pm_runtime_force_resume() only resumes devices with runtime PM status set to RPM_SUSPENDED. To mitigate these issues, do not allow power.set_active to propagate beyond the parent of the device with DPM_FLAG_SMART_SUSPEND set that will need to be resumed, which should be a sufficient stop-gap for the time being, but they will need to be properly addressed in the future because in general during system-wide resume it is necessary to resume all devices in a dependency chain in which at least one device is going to be resumed.

2025-02-09KVM: arm64: Simplify np-guest hypercallsQuentin Perret
When the handling of a guest stage-2 permission fault races with an MMU notifier, the faulting page might be gone from the guest's stage-2 by the point we attempt to call (p)kvm_pgtable_stage2_relax_perms(). In the normal KVM case, this leads to returning -EAGAIN which user_mem_abort() handles correctly by simply re-entering the guest. However, the pKVM hypercall implementation has additional logic to check the page state using __check_host_shared_guest() which gets confused with absence of a page mapped at the requested IPA and returns -ENOENT, hence breaking user_mem_abort() and hilarity ensues. Luckily, several of the hypercalls for managing the stage-2 page-table of NP guests have no effect on the pKVM ownership tracking (wrprotect, test_clear_young, mkyoung, and crucially relax_perms), so the extra state checking logic is in fact not strictly necessary. So, to fix the discrepancy between standard KVM and pKVM, let's just drop the superfluous __check_host_shared_guest() logic from those hypercalls and make the extra state checking a debug assertion dependent on CONFIG_NVHE_EL2_DEBUG as we already do for other transitions.

2025-02-09RDMA/hns: Fix mbox timing out by adding retry mechanismJunxian Huang
If a QP is modified to error state and a flush CQE process is triggered, the subsequent QP destruction mbox can still be successfully posted but will be blocked in HW until the flush CQE process finishes. This causes further mbox posting timeouts in driver. The blocking time is related to QP depth. Considering an extreme case where SQ depth and RQ depth are both 32K, the blocking time can reach about 135ms. This patch adds a retry mechanism for mbox posting. For each try, FW waits 15ms for HW to complete the previous mbox, otherwise return a timeout error code to driver. Counting other time consumption in FW, set 8 tries for mbox posting and a 5ms time gap before each retry to increase to a sufficient timeout limit.

2025-02-08sched_ext: Fix migration disabled handling in targeted dispatchesTejun Heo
A dispatch operation that can target a specific local DSQ - scx_bpf_dsq_move_to_local() or scx_bpf_dsq_move() - checks whether the task can be migrated to the target CPU using task_can_run_on_remote_rq(). If the task can't be migrated to the targeted CPU, it is bounced through a global DSQ. task_can_run_on_remote_rq() assumes that the task is on a CPU that's different from the targeted CPU but the callers doesn't uphold the assumption and may call the function when the task is already on the target CPU. When such task has migration disabled, task_can_run_on_remote_rq() ends up returning %false incorrectly unnecessarily bouncing the task to a global DSQ. Fix it by updating the callers to only call task_can_run_on_remote_rq() when the task is on a different CPU than the target CPU. As this is a bit subtle, for clarity and documentation: - Make task_can_run_on_remote_rq() trigger SCHED_WARN_ON() if the task is on the same CPU as the target CPU. - is_migration_disabled() test in task_can_run_on_remote_rq() cannot trigger if the task is on a different CPU than the target CPU as the preceding task_allowed_on_cpu() test should fail beforehand. Convert the test into SCHED_WARN_ON().
